Description of key information

The water solubility of Molyvan 855 has been determined to be less than 1.25x10^-3 g/l of solution.  

Key value for chemical safety assessment

Water solubility:
0.001 g/L
at the temperature of:
20 °C

Additional information

Key study

Experimental evaluation of the water solubility resulted in a limit value (actual value <1.25 mg/L, slightly soluble) based solely on a visual assessment.  Due to the limitations of the available experimental methods for this complex reaction mixture, a more accurate value cannot be determined experimentally.  While subsequent computer modeling of individual components indicates that the substance is more likely in the “insoluble” classification range, this study provides a maximum limit of functional solubility in aqueous systems. 

Supporting study

Computer modeling of the water solubility of individual substance components based on quantitative structure activity relationships, QSAR (WSKOWWIN, version 1.42, September 2010, © 2000 U.S. Environmental Protection Agency), resulted in a majority of the estimated values being within the “insoluble” classification range (actual values 0.005 to 0.21 mg/L). The less abundant, higher chain length reaction products, as well as products containing multiple coconut oil alkyl residue groups, are expected to be even less soluble in water.
